- AsioApartment gains a bounded Invoke; the close path uses it (8s cap - a healthy
close is ~5ms). A driver that wedges inside Stop/Dispose can no longer hang a live
driver-switch or the resume path: the caller logs the timeout and abandons the
driver (old park semantics, reclaimed at process exit). Apartment test extended to
pin the timeout path.
- Service self-update is now NATIVE code: a detached copy of the NEW build runs
--service-selfupdate (stop -> CopyProgramTo -> start, every step logged to the
update log). The old PowerShell restart script silently died wherever Group Policy
enforces execution policy (Bypass is ignored there), stranding the service on the
old build. Verb wired through IsServiceInvocation + ServiceEntry; verb-gate test
now pins all six verbs.
- UpdateApplier SwapInNewFiles/RollBack made internal + pinned by a real-folder test:
swap lands exactly the release's files (user files untouched), backup holds the
originals, rollback restores BYTE-EXACT including deleting newly-created files -
the contract that stops a failed update bricking an install.
- RouterPortMapper: discovery callback now checks disposed under the gate, so an
in-flight callback can't re-open the port map Dispose just removed.
Gate 59/59.

Five subsystems that had ZERO coverage - all pure code where a real bug would ship
green because the flow tests only prove packets move, not that bytes are right:
- AudioRingBuffer: wrap correctness, overflow drops OLDEST, DropOldest/TrimFromProducer
semantics, silence-fill + exact underrun/drop counters, oversized-write degrade.
- PcmPack 24-bit codec: +/-1-LSB round-trip incl. negatives (a sign-extension bug =
distortion on the whole PCM path), sign preservation, over-range clamps not wraps.
- RemSoundUpdater tag filtering: server-v* relay tags rejected, numeric ordering
(v5.10 > v5.9), suffix tolerance - what stops a wrong-version auto-update.
- RouterPortMapper.IsCgnatAddress: RFC 6598 boundaries exact (made internal for test).
- NetworkPriority.TryAttach: no-throw smoke on a bound socket.
Gate 52/52.

Verified findings from a multi-dimension code audit, plus the two install-flow bugs:
- Fix Opus encoder use-after-free on a codec/rate change while streaming (guard swap vs encode).
- Fix "both" single-file recording dropping audio + drifting (drain both directions in lockstep).
- Fix broken clip counter, UPnP teardown on exit, auto-update-restart foreground grant, and a
malformed-Opus-format packet orphaning a playout session forever.
- Post-install relaunch now respects start-minimised; uninstall is path-aware so it won't clear a
different copy's run-at-startup.
- Perf/hygiene: cache AppConfig off UI hot paths, fold per-peer EQ+gain into one pass, deterministic
disposal (tray menu, timers, COM shortcut, Process handles, process meter), ring-buffer overflow
guard, receiver session-lock fix, remote-control allow-list moved onto the UI thread.
- Remove dead code (two IsAsioBackend, SessionPlayout.Reset, IsSameEndpoint, RemSoundUpdater
IDisposable); several stale-doc fixes.
Deferred (not in this release): drift-estimator tweak, peer-discovery pruning, uninstall retry-loop,
encryption nonce. Wire format unchanged (interops v3.3-v5.1). Version -> 5.2.

- Recover an unplugged/replugged output sound card automatically (issue #5):
detect the dead WASAPI device and remember the receive-output selection so it
re-ticks and re-opens when the card returns.
- Adaptive per-card WASAPI buffer target sized to each card's pull chunk, held
stable so it never flits about under CPU/network load.
- Consolidate all per-user data (config, profiles, logs, sounds) into one
"user settings and logs" folder; migrate every older layout; exclude it from
the updater so custom cue sounds now survive updates.
- Mic-privacy detector: warn once when a Windows-blocked mic is switched on, or a
profile loads with one already on.
- All warning/notice dialogs now come to the foreground even when minimised.
- Apply volume + mute on profile load (were saved but not restored).
- Crash-safe (atomic) profile/config saves.
- Fix two resource leaks (push-mode capture MMDevice; UPnP DeviceFound handler).
- Remove dead code (baseline-diff machinery, dead ASIO probes, no-op stubs).
- Docs: readme.html, MANUAL.md, About-box changelog and release notes for v3.5.

Headline features:
* Automatic router port opening (UPnP / NAT-PMP / PCP). Opt-in via
Preferences; surfaces external address + carrier-grade NAT detection.
* Lock profile (read-only). New File-menu tick that makes a profile
load-only — session changes don't persist, no save prompt on close.
Unblocks unattended shutdowns (NVDA gone, remote dropped, hibernate)
where the existing save prompt could deadlock.
* Check for updates on startup (default on) + brief countdown notice
before silent updates install, so a launch-time update doesn't make
the app silently vanish.
* "Cue sounds" -> "Audio cue sounds" label clarification.
Bug fixes:
* No sound after the computer wakes from sleep. PowerResumeHandler
rebuilds the audio backend automatically on resume; brief
"Reconnecting to audio driver" splash during the rebuild.
* Receiver audio silent after waking from hibernate. RefreshAudioDeviceLists
now treats a transient ASIO probe failure (returns -1/-1 because the
driver is mid-teardown / mid-reinit) as "retry next tick" instead of
clearing the user's tick selection.
Diagnostic-only changes (gated on the existing Enable-logs checkbox,
zero cost when off):
* AudioStepProbe split into cross-buffer vs within-buffer maxes so log
inspection can tell a real-content sharp transient apart from a
pipeline-boundary glitch. Plumbed through every probe owner.
* New rxNetGapMs + gc0/gc1/gc2 delta columns in the diag log to split
receive-side jitter into network-layer vs managed-runtime causes.
Files touched: RELEASE_NOTES.md + readme.html + 24 source files across
RemSound.Core / RemSound.Sender / RemSound.Receiver / RemSound.App.
Three new app files: PowerResumeHandler, RouterPortMapper,
UpdateInstallNoticeDialog.
Wire format and audio pipeline unchanged from v1.5 onward — v1.5
through v2.1 peers interoperate.
